You have been given a sample of tissue that has open spaces partially filled by an assemblage of needle-like structures. What is the tissue?
- A. Spongy bone
- B. Compact bone
- C. Cartilage
- D. Adipose tissue
Correct Answer: A
Rationale: The correct answer is A: Spongy bone. Spongy bone tissue has open spaces partially filled by needle-like structures known as trabeculae. This arrangement gives spongy bone its characteristic appearance and provides structural support while reducing the tissue's density. Compact bone, on the other hand, is dense and solid, lacking the open spaces seen in spongy bone. Cartilage is a flexible connective tissue without needle-like structures, and adipose tissue is predominantly composed of fat cells, not needle-like structures.
